Impact of dysphagia and malnutrition on the survival of hospitalized patients

Introduction: Oropharyngeal dysphagia (OD) and malnutrition (MN) are highly prevalent among hospitalized patients, with significant clinical repercussions. Objectives: To assess the prevalence, survival and factors associated with OD and MN in hospitalized patients with a high risk of OD. Methods: A cross-sectional observational study with 82 patients aged =70 years and with the possibility of oral feeding admitted in 4 services of a third level hospital during 3 months. The Nutritional Risk Screening 2002 test (NRS-2002) was performed to detect nutritional risk and the volume-viscosity screening test (V-VST) for OD evaluation. Data were collected on the clinical suspicion of OD, days of hospital stay, the number of readmissions and other socio-demographic data. Results: 50.6% had OD and 51.9% MN. In 48.8%, there was underdiagnosis of OD. The median number of days of admission was higher among patients with MN (19.5 days vs 13 days, p = 0.02). Of the total readmissions, 70.8% had MN compared to 29.2% that did not (p = 0.03). Survival among patients who did not survive one year after admission was lower when OD was given (Sig. = 0.04). Conclusions: More than half of the population studied has OD, as well as DN, which increases the rate of readmission and decreases survival at the year of admission. Although there are specific screening methods, their use is not widespread, making it difficult to diagnose OD and its therapeutic intervention. (c) 2022 SEEN and SED.
